Instructions
Extract it in Vanguard's Music or Sound directory then run VGMusic.exe. Alternatively you can run it from anywhere then navigate using the kind-of-ghetto file browser to Vanguard's Music or Sound directory. Typically that directory is something like: C:\Program Files\Sony\Vanguard\Assets\Music\

Notes
Parsing the raw samples and the sample combinations is pretty solid. The combination sequencing seems to be right, though there is a block of data I haven't been able to decipher that may contain loop information or other data.
